Application filed November I Serial N 1 32.326.

To all whom it may concern:

Be itknown that I, HIRAM W. BLArsnnLr, a citizen of theUnited States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements in Systemsof Hand-ling Material; and I do hereby declare contents of receptaclesby elevating the con-.

tents thereof centrally and conveying the elevated material laterally.

With these and other objects in view the invention consists,essentially, in the construction, combination, and arrangement of partssubstantially as more fully described in the accompanyingdrawings,forming part of this application, in which Figure 1 is anelevational view, partly in section, illustrating the invention. Fig. 2is a top plan view of the lower portion of the traveling structure, someof the parts whereof are broken away and the upper part whereof isremoved. Fig. 3 is an enlarged .elevational view, partly broken away,illustrating the actuating mechanism and the elevator. Fig. 4 is afragmental sectional view taken on line 4 4 of Fig. 1. Fig. 5isanelevational view, partly broken away, of a modified form of theelevator construction; and Fig. 6 is .a transverse sectional viewthereof on line 5 5 of Fig. 5.

Similar characters of reference designate corresponding parts throughoutthe several views.

Referring to the drawings, the reference character 1 designates uprightsor posts sup porting horizontal beams or timbers 2, whereon rests .areceptacle or vat 3, preferably having adouble bottom 4, and on eachside of the receptacle or vat 3 are located posts or supports 5,carrying horizontal parallel plates or timbers 6, on which are securedtrack-rails 7, whereon travel wheels 8, the shaft or spindle whereofcarry large gear-wheels9, meshing with pinions 1.0 on apropelling-s'haft,11, provided witha hand-wheel l2, said lshaftlbeing supported upon atraveling structure or bridge uppo fiwdup th he l .511 stantially asshown.

Mountedupon the traveling structure or bridge 13 is ;a motorl-4 or otheractuating apparatus having a drive-shaft 15, carrying fixed and looseband-wheels or pulleys 16.,respectively connected to similar wheels' flupon the propelling-shaft 11 by .a belt or band 18, by means of whichthe wheels 38 may be rotated when it is desired to progress thetraveling structure .by machinerlyyzbut the hand-wheeli12 may beused-for purpose when desired. "lfhe drive-shaft 175 may also beprovided 1a pinion 1'9, meshing with a large gear wcheel 20, loose -upona counter-shaft .21, proyided with a clutch .22, operated by aclutch-lever 23 to throwithe counter-shaft into engagement with thegearwheel 20 as subsequently explained. Formed on or connected with thetraveling structure or bridge is a rectangular frame 24, wherein isslidably mounted a cross-head 25, engag ing threaded elevating-rods26,=car;rying gearwheels 27, meshing with gearwvheels 28 upon verticalshafts 29, carry-ingbeveled pinions 30, engaging similar pinions 31 on ahorizontal shaft 32, and a driven shaft 33 carries a beveled pinion 34,meshing with one of the pinions 31, and also carries a ratchet-wheel 35,with which engages a pawl or dog 36 adjustably connected with a link orpull-rod 37, adjustably attached to a crank 38 on the counter-shaft 21,before mentioned. By means of this construction the cross-head 25 can belowered automatically by means of the threadedvrods 26' engaging theends of said cross-head and carrying gears 27, meshing With the gears 28upon the vertical shafts 29, also carrying the beveled pinions 30, en-

' gaging the pinion 31 on, the horizontal shaft 32, rotated by thepinions on the driven shaft 33, which is actuated by theratchet-and-pawl device operated by the counter-shaft 21 when the clutch22 thereon is in engagement with the gear-wheel 20, meshing with thepinion 19 on the drive or motor shaft 15, as before stated.

If it is desired to elevate or lower the cross head 25 by hand, this maybe done by means of the crank-handle 39 upon the shaft 40, carrying thepinion 41, meshing with a large gear-wheel 42 on the driven shaft 33,before 'sition, and the long arm of said bly connected with a belt-shift47, constructed to shift the belt 45 from the fast to the on the shaft33, as will be readily understood;

but when the belt 45 is on the fast pulleys 43 and 44 the cross-head 25can be quickly and positively raised or lowered from the power generatedby the motor 14, transmitted through the motor-shaft 15, fast pulley 44gear-wheel 42 on a driven shaft 33 and parts thereon, belt 45, fastpulley 43 on the shaft 40, carrying a pinion 41, meshing with the beforementioned.

In order to prevent the cross-head from being elevated too far whenbeing raised mechanically, as last before explained, a bellcrank lever46 may be mounted above the cross-head 25, so as to be en aged therebywhen the latter is elevated to 1ts highest polever is flexiloose pulleys43 and 44 and stop the elevating mechanism when the cross-head iselevated.

Suitably supported from the cross-head is a hollow shaft or casing 48,carrying at the lower end thereof a collar 49, supporting radial arms50, carrying revoluble concavoconvex disks 51, constructed when the arms'50 are rotated by the revolution of said casing to progress or turnover the material in the receptacle or vat 3 toward the center thereof,where it is taken up by the buckets '53 upon the endless elevator 54,passing over rollers55 in the opposite ends of said casing or hollowshaft 48, which latter is preferably provided with grooves 56, engaginglongitudinal feathers in the hollow gear-wheel 57,

meshing with the pinion 63 on the countershaft 21 and surrounding saidcasing upon said traveling structure or bridge, whereby said casing canbe elevated by said crosshead.

Revoluble disks 52 are preferably mounted on the shaft of the lowerroller 55 to facilitate the, action of the buckets 53 and areconstructed ,to travel around with the revolution of the'casing, as willbe understood.

Upon the casing or hollow shaft 48 is a flanged collar 58 to supportwheels or rollers 59, carrying a rotatable receiving ring or platform"60, above and in contact with which is supported by depending hangers61 a ringor band 62 to prevent the accidental discharge from saidplatform 60 of the material discharged thereon.

The receiving ring or platform 60 is preferably rotated by means of anelectric motor '89 or other driving apparatus, on the shaft whereof ismounted a pinion 64, meshing with a gear-wheel 65 on a cross-shaft 66,preferably constituting the shaft of the upper elevator-roller 55 andcarrying a beveled pinion 67, engaging a similar pinion 68 on a verticalshaft 69, carrying a pinion engaging an internal gear 70, connected withsaid platform 60 around the hollow shaft or casing 48, substantially asillustrated particularly in Figs. 2 and 3 of the drawings.

Formed on or connected with theupper portion of the hollow shaft orcasing 48 is a cap or solid end 71, carrying a cylindrical extension 72,movably mounted in a bearing 73 in the upper portion of thesupporting-frame 24, Fig. 3, and connected with said cap is a curved arm74, havinga flaring end or plate 75, adapted to travel in a verticalguideor trough 76, constructed to receive the material dischargedthereinto from the rotating platform 60 by the action of the scraper 77,preferably attached to said ring 62, as will be readily understood.

The lower portion of the guide or trough 76 is preferably cut away, asat 78, to receive an endless cross-conveyer 79, (which may discharge atone or both ends of the bridge,) passing over end pulleys or rollers 80,mounted upon the traveling structure or bridge, the shaft .of one ofwhich rollers is extended and provided with a pulley 83, connected by abelt84 with a pulley 85 on the shaft carrying a pinion 87, meshing withand driven by the gear wheel or ring 57 to drive the conveyer 79,substantially as shown.

It will be understood that the cross-conveyer 79 is constructed todischarge the material received from said rotary platform 60 into ahopper 81, mounted upon the end of said structure, which hopper directsthe material upon an endless discharging-conveyer 82, suitably mountedto travel adjacent to the tracks whereon the traveling structure orbridge is mounted.

The operation of this invention will be readily understood from theforegoing description when taken in connection with the accompanyingdrawings and the following explanation thereof. After the receptacle orvat has been filled with material the traveling structure or bridge isprogressed thereover either by means of the hand-wheel 12,propelling-shaft 11, inion 10 thereon, and gear-wheels 9 on the shaftsof the supportingwheels 8 of the bridge or by machinery throughthemediation of the motor-shaft 15, pulleys 16 and 17, andpropelling-shaft 11, as before stated. Then the excavating apparatus islowered into the receptacle in either of the ways before mentionedthatis to say, by the shaft 40, pinion 41 thereon, gear-wheel 42 on thedriven shaft 33, pinion 34 on said shaft, beveled pinions 31 on theshaft 32, pin- IlO ions 30 on the vertical shafts 29, gear-wheels 28 .onsaid shaft, gear-wheels 27 on the threaded rods 26, engaging thecross-head 25, carrying the casing 48, supporting the excavator, asbefore statedor the excavator can be lowered or elevated by means of themotor-shaft 15, fast pulley thereon connected by the belt 45 to the fastpulley 43 on the shaft 40, carrying the pinion 41, meshing with thegear-wheel 42 on the driven shaft 33 and, through the mediation of theparts, driven thereby, as just described. The excavator can be loweredslowly and automatically by means of the motor-shaft 15, pinion 19thereon driving the gear-wheel 20, (fast on a counter-shaft 21 when theclutch 22 is in engagement therewith,) the crank 38, pull-rod 37, pawl36, ratchet-wheel 35, and beveled pinion on the driven shaft 33, drivingthe pinions 31 on the shaft 32 meshing with the pinions 30 on thevertical shafts 29, driving the threaded rods 26. The excavator isrotated by the revolution of the casing 48, revolved by the gear-wheel57, driven by the pinion 63 on the motor-shaft 15, as before stated, andwhen the excavator is so rotated it progresses or turns over thematerial toward the center of the receptacle, where it, is taken up bythe elevator 54 and discharged upon the rotating platform 60, preferablytraveling in the same direction to that of the casing 48, as indicatedby arrows in Fig. 3, from which platform the material is scraped off bythe scraper 77 into the trough 76, through which it falls upon the uppercurved lead of the cross endless conveyer 79, that discharges thematerial upon the discharging-conveyer 82'to be conveyed thereby to theplace of deposit or for further treatment.

Referring now particularly to Figs. 5 and 6 of the drawings, there isillustrated a modified form of the elevator construction hereinbeforedescribed and shown, wherein there is employed a solid shaft 90,carrying the excavator-arms 50 and having mounted parallel thereto pipesor conduits 91, adapted to receive the endless elevator 54, which passesover wheels or rollers 55, adjacent to each end of said shaft,substantially as before stated, and a large gear-wheel 92 is featheredupon said shaft and incloses the tubes or conduits 91, substantially asillustrated in Fig. 6 of the drawings, and a gear-wheel 92 is driven bythe pinion 63 upon the countershaft 21, essentially as hereinbeforeexplained. By means of this construction the elevator maybe arrangedeither inside or outside of the support for the excavator, as may befound most desirable in practice.

The operation of the modified construction just described will besubstantially similar to that hereinbefore explained, and furtherdescription thereof will not be required.

It is not desired to confine this invention to the specificconstruction, combination, and

arrangement of parts herein shown and described, and the right isreserved to make all such changes in and modifications of the same ascome within the spirit and scope of this invention.

I claim 1. A system for handling material having a rotary hollow shaft,an elevator therein, a frame attached to said hollow shaft and aplurality of rotating disks carried by said frame to deliver material tosaid elevator.
